On Monday, Hamid Reza Asefi, official spokesman for the Iranian Foreign Ministry, turned down the reports by certain diplomatic sources on the discovery of enriched uranium in Iran.
"It is not up to diplomats to make such allegations. It is the prerogative of the International Atomic Energy Agency", Mr. Asefi told the journalists.
"Wait till IAEA specialists voice their opinion in Geneva in September, where a report on the Iranian nuclear programs is to be heard", he added.
Mr. Asefi also stressed that Iran's cooperation with the International Atomic Energy Agency was fully transparent and the recent visits to Iran by two IAEA delegations were a confirmation of the frankness and truth of the dialogue.
Earlier, some media reported with reference to diplomatic sources that enriched uranium, which can be used in the production of nuclear weapons, had been found in Iran.
